COAL CLEANING AND SEPARATING MACHINE.

Specification of Letters Patent.

Patented Aug. 5,1913.

Application filed February 24, 1909. Serial No. 479,699.

To all whom it may concern:

Be it known that I, VVALLACE S. AYRES, a citizen of the United States, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Coal Cleaning and Separating Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to coal cleaning and separating machines, especially to that class of machines represented in Patent No. 798,385, granted August 29, 1905, to this applicant, and has for an object to provide improved means for separating the coal from the slate and other matter with which it is ordinarily associated.

A further object of the invention is to provide, in a device of this class, a feed-pan and battle plates adapted and positioned to spread out any massed pieces of coal and slate as they are moving slidably across the inclined floor of the separator, so that such moving floor will have a better opportunity of action, without interference, upon the pieces of slate.

VVit-h these and other objects in View, the invention comprises certain novel constructions, combinations and arrangements of parts, as will be hereinafter more fully described and claimed.

Figure 1 of the drawing forming a part of this application is a top plan of a traveling separating floor with the improved feedpan and baffle-plate associated therewith. Fig. 2 is a view partly in elevation showing one inclination of the traveling floor and showing in section the feed pan, the section being taken on a line approximately coincident with the left hand edge of the floor as it appears in Fig. 1. Fig. 3 is a view in vertical section showing the opposite inclination of the floor. Fig. 1 shows the feed pan partly in section and partly in elevation, the section being taken on line immediately adjacent to the outer edge of the pan.

The traveling floor 1 shown in the drawing is disposed with the corner 2 the lowest, the inclination of such floor being greater than the angle of repose of the coal and less than the angle of repose of the slate. Across the traveling floor 1 a guide bar 3 is extended similar to the guide bar 17 shown in the above mentioned patent, with a feed-pan 1 positioned to discharge coal from the screens or other source upon the surface of the traveling floor 1 and at any desired distance above the guide bar 3 by the location of the bolts 21 and 22, engaging holes 23.

The feed-pan 4 is provided with a bottom having several segments presenting a series of increasing inclinations. The illustration shows three segments 17, 18 and 19, and the arrows show the downward directions of their inclinations, although any number of these segments can be provided at will. It is obvious that a large number of segments may be so connected. A number of segments connected as described form a warped surface. The mixture ofcoal and slate passing down the feedchute 20 enters upon the feed-pan 1 in the direction shown by the arrow in suchchute and is delivered from it in direction parallel to the guide 8. This series of increasing inclinations effects a change of direction in the stream of material fed upon the feed-pan and without the destructive impact that would occur when using but one inclination of the bottom of the feed-pan, and also a comparatively uniform velocity of delivery upon the separating floor. These increasing inclinations of the segments of the bottom also cause the coal, which runs more rapidly than the slate, to tend to crowd the slate to the higher edge of the stream as it enters upon the separating floor.

Upon the top of the guide bar 3 a plate 5 is secured, provided with a plurality of openings 6 to any of which may be pivotally secured angle braces 7, such braces comprising a body portion pivoted to the plate and an upstanding flange portion 8 against which a bar 9 is disposed and secured in position in any approved manner, as by the pivot bolt 10, which also secures the plate 7 to the plate 5.

The brace plate 7 is provided with a segmental slot 11 adapted to engage a pintle 12 in one of the spaced openings 6 of the bar 5, and by means of which the angular position of the brace 7 relative to the plate 5 may be adjusted. The bars 9 are also provided with a plurality of holes or openings 13 by means of which the bars 9 may be adjusted longitudinally relative to the brace plates 7. At their extremities the bars 9 carry baffle plates comprising a flange secured to the bar 9 by means of pins 15 and with web portions extending downwardly adjacent to the surface of the traveling floor 1. At the end of the traveling floor 1 opposite the feed-pan 4., means for receiving and conducting the coal, as the tail-apron 16, is provided. The traveling floor is mounted upon suitable rollers 25 and 26, these rollers being jo-urnaled at 27 and 28 in bearing blocks 29 and 30. One of these bearing blocks is stationary and the other is slidable in order to provide for adjustment. The blocks are mounted in a suitable frame 31 and the device is supported upon an inclined framework 32 pivoted at 33 upon a base portion 34. The adjusting device 35 provides means for varying the inclination of frame 32.

In the specific construction shown in the drawing, the floor 1 travels in the direction indicated by the arrow, so that being inclined at an angle greater than the angle of repose of coal disposed upon said surface, the coal discharged from the chute 4: has a tendency to travel toward the lowest corner 2 of the floor, irrespective of the movement of the traveling floor 1. The guide 3 is positioned to prevent the separated coal from passing over the lower edge of the traveling floor, so that it normally passes downwardly along the upper edge of the guide bar 3 and is discharged upon the tail-apron 16. As, however, a considerable quantity of pieces of slate and other foreign material are ordinarily associated with the coal, the tendency of certain massed groups of them is to follow the course of travel of the traveling floor 1, and they are thereby deflected from the course sought by the included pieces of coal, viz z downwardly against the guide 3. Consequently an intermediate path is fol lowed by these massed groups and the baffleplates 1.4: are interposed in their path for the purpose of spreading out these groups as the same pass downwardly and impinge upon the upper surface of the baffles, and to separate such coal and slate so that the traveling floor, which is disposed at an angle less than the angle of repose of pieces of slate, may act upon such slate without interference and carry such pieces of slate therewith and dump them over the higher edge of the floor shown at the lower edge of the drawing, it being understood that the floor is traveling in the direction indicated by the arrow.

Different conditions of coal, as to quality, shape of pieces and other conditions, make the adjustment of the baffle-plates necessary. or desirable, and several adjustments are provided for. The number of bafileplates and associated parts shown in the drawing are to be understood as only representative, such number being varied at pleasure, in operation, and the position of the arms 9 in parallelism with the line of travel of the traveling fioor is also representative, it being understood that the angle of such arms can be varied at will, as well as the length of such arms, to secure any desired adjustment of the baftleplates relative to the floor, to the feed-pan and to the guide bar 3.
